Demi Lovato - About 'Mistake' lyrics

[Demi Lovato talking about Mistake] "When I first heard 'Mistake', it was the lyrics who caught my attention. I was really intrigued by the fact that, you know, the girl had just been broken up with and it was the other person's fault, it was the other person's greatest mistake. So I thought that was really interesting, as different take on a break up, rather than sitting around and feeling heartbroken you can listen to it and feel kind of a (?), thinking, like, 'I'm not gonna let this get me down, it was his greatest mistake', so I loved the message of this song and I hope you do too!"
